I am looking for remedy for my father in law who is 84 got knee replacement one year back and bypass heart surgery and back surgery around 10-20 years back respectively. On regular CGHS medication but after knee surgery, his knees are ok no pain etc. But he lost strength to pick his feet and feel heaviness. He is now diagnosed with Severe Cervical problem and not in a position to pic up the things and hands shivering. Do not afford to have any further surgical treatment. He is now mostly bed ridden. He can sits few hours in a day by taking some support but can not able to stand even with walker due to loss of strength. Any good remedy for getting strengthen the nervous system so as to able to do his personal daily work. Any good diet to improve his health.
